Not really surprised. They are either short of crew of going tech all the time. Last weekend they were looking to subcharter an aircraft for their IT flights to Italy (W-pattern from EMA and LBA to VRN). In the end they had to use a 737 from Czech carrier Fischer to carry their 80 pax !!!! Today we got a call for the same thing again !!! Two weekends running. When there is no time to prepay for these flights, your choice will obviously be somewhat limited. I just hope they get their house in order.
